Excel/POI - Here We Go Again

All,

Now that I've got an actual s/sheet back from a salesman in the field, the 
problems begin again. The HSSF_OPEN proc is failing as below. 

The statement is: book = 
HSSF_open(/bq_budgets/inbound/dayton/B7_DAYT_S001_STEVETWAMLEY_C7.xls); 
(This s/sheet definitely exists in the IFS. I used a CPYFRMSTMF to copy it 
and it worked fine.) 

Strangely, the 'open' returns an address of ZERO for 'book' but does not 
halt. The exception occurs only when the HSSF_GETSHEET fails because the 
'book' address is 0.

Can anyone please help? Management believes I can read in all 295 s/sheets 
we sent out!! (And I don't want to disabuse them of the notion).
Thanks.

Note the odd wording in the "Unable to construct record instance" line.
